Mechanical Expanding Core Chucks

Antech Converting are the exclusive agents of Panzeri Expanding Core Chucks in the UK. Having been the supplier of Mechanical Expanding Core Chucks for a worldwide leading supplier of Converting equipment, Panzeri have recently decided to exclusively market their products under their own brand name.

The company was founded in the 80’s by Alessandro Panzeri, chief mechanic of a leading company in the paper converting industry. Having detected recurring problems due to reel slippage and the subsequent problems with the damaged cardboard core, he designed, manufactured and patented the first expanding core chucks. These chucks proved to be successful in the market place and nowadays the company is still known to produce the best core holding system.

7500 TR Series Torque Activated Mechanical Expanding Core Chuck

Torque-activated expanding core chucks are fitted with segmented sectors (“leaves”) that expand using the torque of the movement of the reel; this creates optimal centring of the chuck in the core. Torque-activated core chucks are available in numerous diameters, single-diameter or double-diameter versions. Self-expanding and self-centring, locking in both rotation directions, built in treated steel to enhance its hardness with a rust-proofing treatment. The Pads are guaranteed to expand even on low torque values. Chucks are available for sizes ranging from 70 mm to 12” versions. Single-diameter version is available with the flange for the ejection of the core of the spring and flange for the ejection of the core

High load & Torque capacity.

Bi-directional operation.

Synchronised concentric pads.

Very little maintenance required

7500 TR Series Torque Activated Dual-Diameter Mechanical Core Chucks

The chucks have the same characteristics as the TR series of Mechanical Chucks but are supplied with 2 different diameters, making it possible to work on different core diameters without dismantling the chuck.

No Changeover required for different core sizes.

7500 TRM Series Modular Torque Activated
Mechanical Expanding Chuck

The characteristics of TR series of Mechanical Chucks (dimensions, uses, etc.) are maintained, but the TRM range of chucks allows quick interchangeability of the core adaptors onto one centre spindle. This makes the chuck versatile for applications where various core sizes are used. A quick change of core size can be achieved by removing the Central bolt and replace by fitting a different size hub.

High load & Torque capacity.

Bi-directional.

Synchronised concentric pads.

Fast and simple in-situ maintenance.

Rapid changeover of different core sizes

7600 Series Air Mechanical Chucks

Pneumatic Mechanical Chucks are ideal for high weight high torque shaftless applications. Due to their versatility, they can be used in many different fields: paper converting, corrugated cardboard, non-woven, medical and labelling, on various types of machines including slitter rewinders, unwinders and any shaftless machines. The chucks can be supplied with Expanding adaptors which utilise the chuck to expand, to suit a larger core diameter.

The Axial Side Pressure Chucks expand by axial compression of the chuck using side pressure from the Reelstand which guarantees the high grip of the chuck. The Chucks can be supplied as single-diameter core chucks of 3″, 4″, 5″, 6″ and 12″ diameters. Single-diameter lug core chucks models are available with a central bore for a photocell and/or with a flange for ejection of the core.

The Dual Diameter chucks have the same characteristics as the Single Axial Side Pressure Chucks but are supplied with 2 different diameters, making it possible to work on different core diameters without dismantling the chuck. The double-diameter model is available with 3″/4″ and 3″/6″) diameters, however other combinations are available.
